Precision Twist Drill 6000203 Taper Length Drill Bit

Product Description

The PRECISION TWIST DRILL 6000203 is a taper length high speed steel drill bit with a 0.2130 inch diameter and a 118-degree standard point angle. Part of the Series R52 lineup, this bit features a bright/uncoated finish, a right-hand spiral flute, and a straight shank. The overall length is 6 inches with a flute length of 3.625 inches, giving it the extended reach characteristic of taper length geometry. Designed for general purpose drilling, it suits machinists, maintenance technicians, and fabricators working across a wide range of materials in production and job-shop environments.

This bit is suited for drilling alloy steel, carbon steel, stainless steel, cast iron, malleable iron, aluminum, aluminum alloy, brass, bronze, high strength bronze, copper, magnesium, magnesium alloy, nickel, nickel alloy, graphite, cermet, and reinforced plastic materials. The taper length body provides better rigidity than jobber length on deeper holes while still fitting standard drill chucks. It is a practical choice for CNC and manual drill press work where reach beyond a standard jobber bit is needed without stepping up to aircraft extension tooling.

Compatibility

Designed as a general purpose taper length drill bit compatible with standard drill chucks accepting straight shanks. Verified material applications include alloy steel, aluminum, aluminum alloy, brass, bronze, carbon steel, cast iron, cermet, copper, graphite, hardened steel, high strength bronze, magnesium, magnesium alloy, malleable iron, nickel, nickel alloy, reinforced plastic materials, and stainless steel.

Installation Notes

Install in a compatible straight-shank chuck and verify secure seating before operation. Always wear appropriate eye protection and secure the workpiece before drilling. Reduce feed rate when breaking through the far side of a workpiece to prevent grabbing or bit deflection. Follow applicable shop safety standards and machine manufacturer guidelines for speed and feed recommendations based on material type.
